input: add I2C to config since the driver makes several i2c*() calls

Add to help text that the Intel I2C ICH (i801) driver is also needed
for this kernel.

Add LEDS_CLASS to config since the driver makes les_classdev_*() calls:
ERROR: "led_classdev_register" [drivers/input/misc/apanel.ko] undefined!
ERROR: "__led_classdev_unregister" [drivers/input/misc/apanel.ko]
undefined!
